ignition voltage) of the ballast output stage. Should this
voltage exceed the internal threshold of 1.2 V (V CSTH+), the
ignition regulation circuit controls the voltage on the VCO
pin to increase the frequency slightly (see Fig. 6). This
cycle-by-cycle feedback from the C S pin to the VCO pin
will adjust the frequency each cycle to limit the amplitude
of the current for the entire duration of ignition mode.

When C PH exceeds 2/3*V CC (V CPHRUN+ ) for the second
time, the IC enters run mode and the fault counter
becomes enabled. The ignition regulation disabled in run
mode but the IC will enter fault mode after 65 (n EVENTS )
consecutive over-current faults and gate driver outputs
HO, LO and PFC will be latched low.

The output voltage of the ballast will increase during the
ignition ramp t RAMP because the frequency ramp down
from the preheat frequency to the ignition frequency and
will be constant during ignition because the ignition
regulation circuit will regulate the amplitude of the current

for the entire duration of the ignition time t IGN (Figs. 7 and

During ignition mode, the PFC circuit is working in high-
gain mode and keeps the DC bus voltage regulated at a
constant level. The high-gain mode is necessary to
prevent the DC bus from decreasing during lamp ignition
or ignition regulation. Also during ignition mode, the
SD/EOL fault is disabled.
